Based on the list above the correct properties of solids are;
B) has a rigid shape that does not change easily
E) has particles that can wiggle but cannot move
Solids have a variety of properties that make them different from liquids and gasses. Their particles are fixed making them rigid and hard to change shape. The particles also have a low kinetic energy making it hard for the particles to vibrate. In addition to those properties, solids cannot be compressed into smaller sizes.
I do not understand your question..
Answer:
Frequency
Explanation:
The property of waves that remains unchanged as it crosses the boundary of one medium to another is the frequency of the wave.
As a wave moves from one boundary to another, the wavelength and the speed of the wave changes.
The speed of the wave is product of wavelength and frequency. Also, the wavelength of the wave is function of the distance between successive crests or troughs of a wave.
The frequency of a wave is the number of waves that crosses a medium per unit of time.
